I am going to purchase a new Dell PowerEdge 2850 server with RedHat Enterprise Linux 3 and I need some help selecting a Fibre Channel Host Bus Adapter (HBA). I have never used Fibre Channel HBA's before, but the device that we are going to connect has multiple 2Gb channels but we will only use one. I understand that in theory a 2Gb fibre channel HBA is enough, but what else do I need to look for?
- I want to buy one that is available on Dell.com so that I can get it installed and shipped by Dell.
- What brand should I buy with my setup?
- What I am looking for on these HBA adapters, do I use PCI or PCI-E?
- Is PCI-X and PCI-E both the same (PCI-Express)?
- Any other helpful info you can give me.
Here is the page at Dell.com that lists all the Adapters:
I see EMULEX and QLOGIC, and I have read here at Experts Exchange already that RedHat seems to have brilliant support for QLOGIC, but didn't dig deeper.
Again, this is the first time I am using a Fibre Channel HBA and I have got no idea about it. This is a server I purchase for a remote location, so I will probably never be able to touch it.
